Is it possible to build link and run a Fortran dll built using Visual Fortran Compiler XE 188.8.131.52 [Intel(R) 64] in Visual Studio 2010 to a c++ program built using visual studio 2012.
Do I need to rebuild the dll using visual studio 2012 ?
It seems likely to work without rebuild, in the absence of any specific information.
I agree with Tim - it should work without changes. You will need to have the Visual C++ 2010 runtime DLLs installed to run the program, though. Microsoft supplies these for x86 and x64.
